Apple said iPhone 2G hardware can’t handle MMS, but the truth is not. There are plenty of tutorials that helps to enable iPhone 2G MMS, but it would be complicated for some users. If you have jailbroken the iPhone, you can just enable it with simple installation. Find “ActivateMMS2G” in Cydia. It’s in the iSpazio Source. If you can’t find it, install iSpazio from “Repositories”. Install “ActivateMMS2G” and restart the iPhone. Configure the MMS server settings in “Settings” > “General” > “Network” > “Cellular Data Network”. You are done.
